i have a very long list of reasons that derpy works better then twi in this but its late and im way to tired to sit here trying to convince you to leave the dark side! (the side of the twi lover/ derpy hater)
"Oh, Derpy? Err, she may LOOK somewhat stupid, but we had her IQ tested, and it turns out it's at the "impossibly genius" level at 420! I never thought to test it at first, but one day I was rambling to myself about thermonuclear physics, and she understood every word I said! Brilliant, right?? She even had a conversation with me about how peculiar Cesium atoms are. She never ceases to amaze me with her hidden intellect. I ponder to this day, if she simply pretends to be clueless to fit in, and-oh. Ohhhhh. I now understand why that new company that produces all those complex arcane devices is named 'DƎRPYTECH'."
